( ×.... Question from @hofifahhafni

( $(\sqrt[3]{ \sqrt{25 ^{3} } } ) ^{2}$ × $(0,5) ^{-2}$

ahmedhabib047 $\sqrt{25 ^{3} } = \sqrt{5 ^{4} } = 5^{2}$
$\sqrt[3]{5^{2} } = 5 ^{\frac{2}{3}} 

 (5 ^{\frac{2}{3}} ) ^{2} = 5 ^{{\frac{2}{3}} x 2} = 5^{{\frac{4}{3}} 

$

Bilangan prtama sudah , sekarang bilangan kedua
$(0,5) ^{-2} = \frac{1}{0,5 ^{2} } = \frac{1}{ \frac{1}{2} ^{2} } = \frac{1}{ \frac{1}{4} } = 4$

ahmedhabib047 waduh sulitnya ngetiknya , tolong hapus admin , aku ngedit berkali - kali tak bisa ....

okymarkianto $(\sqrt[3]{ \sqrt{25 ^{3} } } ) ^{2} \times (0,5) ^{-2} \\\\
 (\sqrt[3]{ \sqrt{5 ^{6} } } ) ^{2} \times (\frac{1}{2}) ^{-2} \\\\
 (\sqrt[3]{ 5 ^{ \frac{6}{2} } } ) ^{2} \times (2^{-1}) ^{-2} \\\\
 (\sqrt[3]{ 5 ^{ 3 } } ) ^{2} \times 2 ^{2} \\\\
 (5 ^{ \frac{3}{3} } ) ^{2} \times 4 \\\\
 5^{2} \times 4 \\\\
25\times 4\\
